MACHINE FOR RAISING wir on FABRICS.

Application filed April 24, 1915. Serial No. 23,632.

by declare the following to be afull, clear,

and exact description of'the invention, such as will enable othersskilled in the art to which it appertains to make and use the same. 1 i

This invention relates to machines for raising nap on fabrics and hasfor its primaryfobject to provide a construction in which the raisingaction may be eflected simultaneously in the direction of the warp ofthe fabric as well as transversely of the.

same, whereby an even and highly efficient raising action is obtained.

Other objects of the invention are to provide a machineof this characterin which the fabric is conducted over two different groups of raisingrollers which are rotatably mounted, partly in the direction of the warpand partly'in that 'of the weft of the fabric, in a traveling carriagemovable to and fro transversely to the traverse of the fabric, and theraising rollers of oneof which groups are adjustable in verticaldira'ising action; I

With these and other ends in view my invention consists in thearrangement, construction and combination of parts; to be hereindescribed and particularly pointed out in the appended claims.

In the drawings Figure 1 is aplan view of a machine constructed inaccordance with the presentinvention, some parts of the guiding rollersfor the fabric being broken oif for the sake of clearness; I V j Fig. 2'is a front elevation of the machine; .Igigft is a side elevation of thesame; an I justable bearing rollers.

able power source. When this shaft is rotated it imparts a to and fromotion to the carriage 5. Transversely of this carriage, shafts 11 to 18are'mounte'd on the same which are situated parall'elly to each otherand in the same horizontal plane. The shafts 11 to 18 have securelyplaced thereon the raising rollers 19 and are rotatably mounted in'bearngs 20.;of the carriage .5.

As is to be seenfrom the drawings, two raising rollers 19 are mounted oneach of the transverse shafts. shafts 11 to 18 are arranged so closelyto one another that the raising rollers of two adjacent shafts cannotbearranged oppositely to. one another; the rollers are arranged instaggered relation so that the rollers of one shaft always face' freeparts of the adjacent shaft. These rollers 19 execi'ite a raising actionin the direction of the Weft threads of the fabric. j

The raising rollers 19 fastened to the form four rows on linestransverse to the direction of the axes of their shafts.- Between theserows spaces 21, 22, 23 are left which serve for the reception of anothergroup of raising rollers, indi- -'cated by These 'thenumerals 24,125,26. rollers are mounted in bearings 27 fastened to the'carriage frameand serve to eifect a fabric in the direction of-itswarp threads. v

The raising rollers 24, 25,26 are vertically adjustable in height. Forthis purpose the bearings 27 for the rollers are so construct ed as topossess an adjustability in vertical direction. Referring particularlyto Fig. 1, the'bearings 27 consist of an upper part 28 comprisingth'e-'brasses and cap-piece, and a lower part 29 forming a base fixed tothe carriage frame. Both parts are of a screw bolt 80, which in one partis provided with right handed thread and in the other part with left'handed thread. The upper part 28 is provided with recesses 31 by whichit is guided on corresponding extensions 32 formed on the base 29. Byrotating the screw bolts '30 in one direction the upper parts of thebearings together with the rollers mounted therein are raised and byrotating the belts in the opposite direc'tion The rotation of the screwbolts may be effected by means of a rod; by inserting the same intorecesses connected The raising rollers of both groups usually form onecommon horizontal contact surface for the fabric to be raised. Due tothe adjustability of one roller group with respect to the other theraising action can be easily controlled at will. If the rollers 24, 25,26 are so adj usted. as to raise above the upper contact surface formedby the rollers 19 the raising action will be more efficient in thedirection of the warp threads of the fabric, While if the aforementionedrollers are lowered so far as to be under the upper surface of therollers 19, these latter will execute a more efiective raising action onthe fabric in the direction of its Weft threads. Besides, the rollers24, 25, 26 can be lowered so far that they will no longer come intocontact with the fabric on which the nap is to be raised, thus remainingin a non-operative position.

Underneath the raising rollers two electric motors 34 and 35 arefastened to the frame of the carriage 5, which serve to drive therollers. 7

Motor 34 imparts rotation to the shaft 11 through the medium of an openbelt 36 and motor 35 imparts rotation to the shaft 16 through the mediumof an open belt 37 too.

The driving shafts of the motors 34 and 35 revolve in oppositedirections. From the shafts 11 and 16 rotation is transmitted to theremaining shafts 12, 13, 14, 15, 17 and 18 by means of open and crossedbelts, as shown, in such a manner that each two rollers which aresituated one opposite to the other always rotate in opposite directions.

Mounted in brackets 41 at the front and the rear end of the carriageframe 5 are shafts 38 and 39, respectively. Shaft 38 is rotated by themotor 34 and shaft 39 by motor 35 through the medium of open belts 40.

The shaft 38 transmits its rotation to the longitudinal raising roller25 by means of a half crossed belt 42, and in similar manner shaft 39transmits the rotation imparted thereto to the longitudinal raisingrollers 24 and 26 by means of two half crossed belts 43. According tothis arrangement, roller 25 will rotate in a direction opposite to thatof the rollers 24 and 26.

Pairs of rollers 45, 46 are mounted in the upper ends of standards 44and serve to guide the fabric 47 through the machine in the direction ofthe axes of the raising rollers 19 and transversely to the rollers 24,25 and 26. The guiding rollers 45, 46 are adjustable in height and forthis purpose their bearings 48 are slidably mounted in any well-knownmanner in the upper ends of the standards 44. Thereby it is allowed tobring the fabric into contact with the raising rollers or to hold itfree from the same. The fabric is further guided by means of guidingrollers 49 rotatably mounted in standards 50.

As to the guiding of the fabric I do not wish to be limited to themechanism illus trated on the drawings, the fabric may also be guided inany other suitable manner; besides the rollers 45, 46 arranged at twosides of the machine, a plurality of guiding rollers may be providedbetween the same.

It is obvious that various modifications may be made in the constructionshown and above particularly described within the principle and scope ofmy invention.
